The newest addition to my household:
Unfortunately the photo doesn't show his full range of colors. The teal and red you can see, but in the right light he also shows purple and cobalt blue.
The shop also had a midnight blue halfmoon betta which was insanely tempting, especially given that it was only about $20 when they sell from breeders for over $50 as a general rule (and by his size he WAS of breedable age) but I forced myself to resist. I can't afford to spend that on a fish right now. Besides, if I get a halfmoon I want an opaque white. Which means I'd better have some cash to throw around first because those run a pretty high price tag... so like, not until I have the setup to actually breed them.
